9.0 MAINTENANCE

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing. This appliance and its venting system should be inspected before use and at
least annually by a qualified service person. The appliance area must be kept clear and free of combustible materials,
gasoline or other flammable vapors and liquids. The flow of combustion and ventilation air must not be obstructed.
1. In order to properly clean the burner and pilot assembly, remove the logs to expose both assemblies.
2. Keep the control compartment, logs, burner, air shutter opening and the area surrounding the logs clean by vacuuming or
brushing, at least once a year.
3. Check to see that all burner ports are burning. Clean out any of the ports which may not be burning or are not burning
properly.
4. Check to see that the pilot flame is large enough to engulf the thermocouple and thermopile and reaches toward the
burner with the third jet.
5. Replace the cleaned logs.
6. Check to see that the main burner ignites completely on all openings when the gas knob for the burner is turned on. A 5 to
10 second total light-up period is satisfactory. If ignition takes longer, consult your Napoleon dealer / distributor.
7. Check that the gasketing on the sides, top and bottom of the door is not broken or missing. Replace if necessary.
8. If for any reason the vent air intake system is disassembled, re-install and re-seal per the instructions provided for the
initial installation.

ADJUSTMENT

10.1 PILOT BURNER ADJUSTMENT

Adjust the pilot screw to provide properly sized fl ame. Turn in a clockwise
direction to reduce the gas fl ow.

10.2 VENTURI ADJUSTMENT

Both fi replace models have air shutters that have been factory set open according
to the chart below:
These settings are for rear vented (maximum) horizontal termination. Adjustment
may be required depending on fuel type, vent confi guration and altitude.
Closing the air shutter will cause a more yellow fl ame, but can lead to
carboning.
Opening the air shutter will cause a more blue fl ame, but can cause fl ame
lifting from the burner ports. The fl ame may not appear yellow immediately;
allow 15 to 30 minutes for the fi nal fl ame colour to be established.
Air shutter adjustment must only be done by a
qualifi ed installer!
To access the air shutter, remove the two screws that
secure the cover to the air housing, taking care not to
damage the gasket.
